Gavin Smith, the father of Southern Cal sophomore forward Evan Smith, has been missing since Tuesday and now is the subject of a police manhunt.

The Los Angeles County Sheriff's Department is seeking the public's help in locating Gavin Smith, an executive with 20th Century Fox for 18 years. He was last seen in his Mercedes 420E sedan on Tuesday evening, near the family's home in Oak Park, Calif. Police say there is no evidence yet of foul play in his disappearance.

"We are very concerned about Gavin," Fox distribution president Chris Aronson told The Hollywood Reporter. "We are actively doing what we can to assist the L.A. Sheriff's department."

His son, Evan, played in only four games last season after sustaining an ankle injury and undergoing surgery. Evan (6-7, 225) left the club via a medical retirement in March but plans to remain at USC and on scholarship but not count against the NCAA's mandated cap of 13 scholarship players.

Gavin was an athlete in his day, too. He was a deep reserve on the UCLA national championship teams of 1975 and '76 before transferring to Hawaii for his senior season.
